That led them by the right hand of Moses with His glorious arm, dividing the water before them, to make Himself an everlasting name?…the Spirit of the LORD caused him to rest: so didst Thou lead Thy people, to make Thyself a glorious name. – Isaiah 63:12, 14

God works His great wonders of grace with the high motive of making known to His creatures His own glory, manifesting what He is and who He is, that they may worship Him. He tells us in the text that He “led them by the right hand of Moses with His glorious arm, dividing the water before them, to make Himself an everlasting name.” So He has done, for to this day the highest note of praise to God that we know of, is the one that tells of the deliverance of Israel out of Egypt, and when this world is burnt up, the song will go up to God in heaven will be the song of Moses, the servant of God, and of the Lamb. Still, if we want a figure and a foretaste of the ultimate victories of God over all His people’s enemies, we have to go back to the Red Sea, and look at Miriam’s twinkling feet, and hear her fingers making the timbrel sound as she cries, “Sing ye to the Lord, for He hath triumphed gloriously; the horse and his rider hath He thrown into the sea.” He did it to make Himself an ever-enduring name, and He has succeeded in that object.

Isaiah adds that the Lord led His people, and brought them into their rest, to make Himself “a glorious name.” God is glorious in the history of Israel. God is glorious in the history of His church. God is glorious in the history of every believer. ~ C.H. Spurgeon
